It is quite immaterial what particular form the cutting machine may take, so long! as it is capable of having the sheet of root'- ing fed thereto and oi cutting it either into shingles or slabs. Any one of a number of cutting machines may be employed for this purpose. i

The cutting nachine, as conventionally shown, comprises a frame 15, which is sup ported some distance from the grounder floor upon a base 16, adapted to be adjusted as to position on the floor by means of casters or rollers 17. At 18 are indicated cutters arranged longitudinally of the machine to cut or slit the web into a number of longitudinal strips or else form a series of longitudinal slots therein, (this depending on whether the machine is for the purpose ot producing individual shingles, or shingle strips or slabs), in the cutting operation the strips being advanced on the machine by means of feed rollers 19 or other suitable means. At 20 there is indicated a chopping cutter adapted to cooperate with a stationary blade (not shown) by which the web is cut transversely so as either to sever the longitudinal strips into shingles of the desired. length or else to cut the sheets transversely in lines intersecting the slots, so as to produce serrated slabs or shingle strips. This machine is shown as simply one ex'emplifh.

cation of shingle forming or slab forming machines, which may be used in combination with instrumcntalitiescmbodyiiu the present invention. [is the units are cut from the web, they slide down a guide 2] and are delivered to an endless conveyor belt 22, the upper stretch of which is prclbrably inclined downwardly and outwardly so that the units carried thereby can be shot from the end oi the conveyor into the stacking mechanism.

Any suitable powentransinitding mechanism may be employed for effecting the teed of the web and the operation of the various cutters. As shown on the dra vings, power is transmitted to the cutting and stacking mechanism through the pulley 24: mounted on shaft 23 and through belt 25 trained about said pulley and connected with any suitable source of power (not shown). Power is transmitted from this main power shaft :23 to the cutting mechanism through gear wheel on shaft which. meshes with the large gear 2? on the chopping cutter shaft 28. From this shaft, the power is transmitted to the cutters l8 and to the feed rollers 19, through a chain of gears 29, 3O, 31, 32 and 33, the first on which is in mesh with gear 34 on cutter shaft 28, which as abovestated, is connected with the main source of power.

in order that the upper stretch of the conveyor 22 may be given the inclination, hereinhetore referred to, the l e t is trained about rollers 35 and 36, the former on shaft 37 journaled in the frame of the cutting mechanism, is at a higher elevation than roller 36 which is located on shaft 38 journaled in brackets These brackets are attached to, the forward. end of said frame, that is on the end toward the stacking mechanism. The conveyor is driven by means or" a sprocket wheelt), on shaft 38 at the "forward end of the belt, which is connected with sprocket wheel 41 mounted on the main power shaft 23 by means of a sprocket chain 42' The conveyor and the cutting mechanism, both operate at a very high speed, the belt, l'iowever, moving more rapidly than the cutting mechanism, so as to receive the units delivered thereto and sepa-.

rate and space them from each other. The reason tor this will appear later.

The principle upon which the stacking mechanism operates will be understood from the diagrammatic illustration in Figure 9. Between two oppositely spaced walls 4? and 44 there is pivoted an inclined agate 45.; having arms 46 and 47 extending upwardly and downwardly from its pivot point. liver or under this gate, as the case'inay be, the units are delivered trom the conveyor. hen the is in the full lineposition, the units pass over the top of the gate into the receptacle a. temporarily formed by the lower arm or reach 47 oil the grate contacting with the lower end of wall 43. When the predetermined number of units have been delivered into this receptacle, the gate is quickly shifted to the dotted line position, so to bring the lower ottsct end of the gate into engagement with the wall at, form- Gen Wardly at an angle as at 182 so as to malre contact was the upper sde oi the when the latter is in position to form receptacle a," -this downwardly bent portion being de signed to form the lower end wall of said receptacle and in a similar manner the lower sheet-metal member of t gate is bent downwardlyat an angle to form the lower end Wall 183- of the receptacle I) when the gate is in proper position. For purposes stability, Wall 182 is suitably braced 3 land the end Wall 183 is braced by angle member 83 placed between the Wall an offset portion 4-8 of the gate, extending from the sheet 68 which is in turn supported by the brace members 85.

The stacks or bundles of elements are delivered alternately from the receptacles o and a over the chutes and 86 into the shaped boxes 88 or an endless conveyor 89 and are. carried "therein to suitable place of deposit Where they are taken from the bones and made into bundles in a manner as hereinbe'fore indicated. The endl chain conveyor 89' carryin boxes 88 are trained about sprocket wheels 90., 91. suitably supported.

lit will be readily understoodthat thee-11d less conveyor 89 is subjected to heavy loads when in operation and for this reasoru has a tendency to sag. To f l V avoid this the sprockets 90 are mounted for sliding" adj niont on the base member l'lll and are adjusted thereon by means oi the feed screw 192 operated by handle to increase the tension ol the conveyor chains.

lt is desirable that'the boxes more with sufficient speed that one box, when it his received its stack, shall be advanced far enough to be out of the Way and tor an other to have been advanced to position receive the next succeeding stack as it is delivered from the stacking machine. il hile speed is not necessary. a considerable anonnt of power is desirable inasmuch the load to be carried is very heavy, and for this rea son there is located at the opg'iositc end of the chain "from that at which the tension adjusting mechanism located, a. power de vice 194 of any desirable character. such a motor or the like, and to which the sprockets 9]. are connected through a chain of reducing gears $3, 94, and 96, n eshing with gear 97 attached to the shaft 5H. of the sprockets, and the gear meshing with pinion 92 on the power shatt. This pulley and the chain of gears are mounted for support on a suitable frame 19 h.

In order to support the conv yor 89 which is comprised of sprocket chains 101 connected by cross bars 102, sprocket Wheels 90, 91 are attached to the shafts 95% said sprockets having thcir teeth in mesh with the sprocket chain.

D/lountmi in the aperture and surrounding the plug 157 is a sleeve i632 in metal or other suitable material. 'lhis sleeve is reduced toward one end to fiirm a shonhlefififi adapted to abut; similar shoulder on the plug to 11 nit itx miiwarrl movement. rrrexv-tln'emied into thwopposiie and of ills sleeve is a cap cunnected with by the engagement of stud 157 ltil having a projection thereon about which is seated a compression spring 165, the other end of the sprinp'being seated in an. aperture 166 in the unreduced portion of the plug and tending to press the plug outwardly to position to ride in the guideways 140. 141 I It isnow obvious from the above construction that the plug or trip member-157 riding in the g 'uideways 14a), 1e11, will be press id inwardly against the pressure of springs 165 when said plugr comes in contact with the bevelled face of either the tripping members M2, 148% and the tubular member 131 will thereby be freed or released to move in vertical direction up or down, the case may be.

in operation, the web of rooting is fed continuously by the usual teed rolls 19, through the unit forming machine, and is formed into units 01' the desired character. The serered units are received by the conveyor 22, which constitutes an intermediate feeding mechanism, which, travelling! at a higher rate or speed than the sheet ot root ing, spaces the units apart in the direction of their travel so that there is an appreciable interval between the rear edge of the next one succeeding it, Assuming that the gate is in the position, (shown in Figure 5), the units pass over the inclined end of theggate and drop onto the lower end of the'gate,

with their Fla-t sides resting on said grate," their further progi being stopped when they abut against the almost "vertical portion of the plate 182. Each unit passes over the preceding unit and a .pile or stack is gradually formed, until. a predetermined number have been stacked. A similar opera tion takes place with respect to the lower wall when the gate is in )osition to term a receptacle therewith. tiring; this time. through the speed reducing scaring, the 115, with pin 130 riifling in slot 132, is caused slowly to rotate, as hereinbet'ore de scribed, and it turns from the position shown in Figures 3 and 10 ot' the drawings, its first tendency is to move the lower reach of the cylindrical member to the right and to carry the plunger downwardly compressing spring the downward movement of'the tube being prevented however, with the arcuate guide 137. When the gear has made approximately one quarter revolution, the lower reach of the cylindrical member 131 moves toward the lett until approxil'nately another quarter revolution is made, the plunger 13?) still deseendin and further compressing the spring. At about this point the plug or trip member 1:37 comes into contact with the bevelled tace of tripping meinher 1462 whereupon the trip member is pressed inwardly against the pressure of spring 1653 and the cylindrical member 131 released and shot suddenly dowi'iwardly L if) the pin 130 w Lessons by the torce of the compressed spring 136. The force thus stored'in the springis sufficient to project the block 159 beyond the lower edge of the arcuate members where the plug or trip member 157 is free to resume its normal position, and thus takes under the. guide.

it is obvious that as the cylindrical member is shot downward that the gate is quiolo lyshifted, and the mechanism then passes througl'i the latter, halt of its cycle at the end of which the gate is again shifted. In this latter half of the cycle, the gate is in contact as hereinbetore set forth, with the lower wall and the operation is similar to that justdescribed and is in detail as follows; The protruding end of the plug or trip member 157 rides on the guideway 141 toward the left, for approximately a quarter revolution of the gear 115, compressing spring 135, and then toward the right until point near the starting point is reached by hen the plug .157 will again be forced inwardly by tripping member 143 and the cylindrical member shot upwardly by the force in the compressed spring 135, again operating the gate to release a stack, of units and form compartment a, so that for every half revolution of thegear 115 there is a stack of units released and deposited in the box 88 of the conveyor and a new compartment or receptacle is formed.

the switch operates, in the manner thus described, the stacks or bundles of units formed in the receptacles are delivered to the boxes of the conveyor whereby they are carried along its course by said conveyor and are lifted. therefrom by workmen and termed into bundles by being'tied or otherwise fastened together either by a machine or by hand. Due to the relation ot parts of the machine, the stacks are delivered to the boxes so that the units thereof rest on one edge and in upright position, making'it easier to handle the bundles when removed from thereceptacles.

in considering the instrun'ientality which l have termed the gate, it will be seen that it performs two dillerent functions, which if desired could be pert'ori'ued by two ditl'creut instruinentalities. "That is, the upper end of the gate performs. the function of a switch for directing the flow of units from the forming or cutting machine, automatically and alternately into sop-a paths. The lower end of the grate serves the inn, tion oi arresting the llozw of diy'erted in until pile or stack the of is formed. 3 have if these eleme for the sake oi simplicity of construction in the l'lZir-llll,
